Topology Optimization of Patient-Specific Custom-Fit Distal Tibia Plate: A Spiral Distal Tibia Bone Fracture

Currently, bone fractures are commonly treated with fixation plates that present rigid designs and stiff biometals (e.g., Ti-6Al-4V) increase the probability of stress shielding happening during remodeling by required stimuli for adequate healing. This can lead to medical implant loosening, resorption possible refracture. In this paper, an initial custom-fit plate is designed be based on computer tomography imaging a patient suffering from distal tibia spiral fracture. The was redesigned reduce risk being shielded. Topology optimization were implemented redesign minimizing strain energy reducing total plate’s volume in three different cases (25%, 50% 75%). A bone-plate construct assembled examined using finite element analysis considering load conditions patient’s gait loaded 10% bodyweight. stresses evaluated order compare topology optimized design. findings show higher volume, transfer reduction increases fractured area reduces shielding. viable approach building
